Best Practice Case Studies-Rectus Femoris Tear

Video Transcription

Video Summary

A 15-year-old female athlete presents with right anterior thigh pain, suspected to be a rectus femoris strain. Radiographs, typically normal for muscle strains, were performed to rule out bony issues. MRI revealed edema in the inner muscle belly of the rectus femoris, suggesting a subacute low-grade strain. The rectus femoris, unique for its muscle-within-a-muscle structure, presents with specific strain grading. Grade 1 shows T2 high signal at the myotendinous junction, while Grade 2 features involve fiber disruption. Grade 3 indicates complete fiber disruption and retraction, often with hematoma. A "degloving" injury is also discussed.
